This parameter is important in determination of the corrosive properties of water, caused by carbonates, bicarbonates as well as dissolved salts. Testing alkalinity is important in the treatment of drinking water, waste water, swimming pools, heating and cooling systems, food and beverage systems, and soil and environmental testing, as well as in agriculture, farming and fish farming. Includes 110 tests.
Minerals are an important part of everything around us -- from the pencils we write with to the airplanes in the sky. Even the earth beneath our feet is packed solid with these essential building blocks. In All About Rocks and Minerals, children will discover the characteristics of minerals and see how different minerals make up different kinds of rocks: igneous, sedimentary and metamorphic. A visit to a lapidary shop examines some beautiful gemstones, while a fun, hands-on investigation demonstrates how solid crystals can be made from a liquid. Part of the Earth Science for Children DVD Series. A teacher's guide is available online. 23 minutes. Grades K to 4.
The Earth Science Book Plus Series provides colorful teaching models and reproducible activity cards that teach children about earth science. The models are made of resilient, non-toxic, EVA foam, with removable pieces that stimulate problem-solving skills and develop small motor skills. The book covers contain background information, activities and extension ideas. Teachers can cut out the task card and use it in a learning center or as a group activity. The models are 10" x 14.5" x 3/4" thick. The teaching model illustrates volcanic action and shows how igneous, sedimentary and metamorphic rocks are formed. Available in French. Grades K-6.

For use with 15297, 04235 and 98388 landform models. Set of 10 lab investigations workbooks includes 20 pages of activities involving students in locating and identifying features on the models, observing, speculating and recording the practical influence of geography upon economic and social activities of man.
With the full-size kit, demonstrate important density concepts to an entire classroom. Challenge students to use scientific inquiry techniques to explore geology, meteorology, freshwater and saltwater systems. Using the illuminated flow of colored fluids, students can visualize abstract concepts related to plate tectonics, sea-floor spreading, air masses, fronts, air pressure, winds, ocean currents, thermoclines, haloclines, upwelling, El Nino and more. Dimensions: 44"L x 6"H x 3.75" W. 72-page manual.
Watch how solids settle in layers at the bottom of a tank. Includes: Acrylics tank, slope, open tube, plastic drain tube and sprinkler head for plastic bottle. Dimensions: Tank - 11.8" x 2.8" x 5.9", Slope - 11.2" x 2.5" x 0.79", Open tube - 13" x 2.5" x 3.1", Plastic drain tube - 3.9"
45 specimens, approximately 1.5" x 1.5", includes 15 each of igneous, sedimentary and metamorphic rocks. Each category of rock is well represented and forms an integrated classroom study unit. Grades 6-12. Ages 11-18.
Fossil fuels were formed millions of years ago as part of a natural process in which the remains of dead plants and animals were buried and placed under extreme pressure and heat. Coal, oil and natural gas are the most important fossil fuels. But what are they used for, how do we find them and what can we do to preserve our limited supplies? Students will find the answers to these questions and more in Fossil Fuels as they explore these nonrenewable resources of Earth. A fun, hands-on investigation demonstrates a creative alternative to using fossil fuels in the creation of plastic and a visit to an oil platform showcases how this valuable fossil fuel is pumped up from the bottom of the ocean. Part of the Earth Science in Action DVD Series. A Teacher's Guide is included and available online. 23 minutes. Grades 5 to 8.
Fossils are historic blueprints -- remnants of plant and animal life that preceded us. In Fossils, students will examine molds, casts and imprints of various living things, and discover how scientists place the age of these ancient remains and the methods they use to preserve them for future generations. Find out how paleontologists discover fossils and what these discoveries tell us about the past. Take a trip to the Petrified Forest, and examine tree trunks that were turned to stone millions of years ago. A fun, hands-on investigation demonstrates for students how they can create four different simulated environments in order to test each for its ability to preserve remains. Part of the Earth Science in Action DVD Series. A Teacher's Guide is included and available online. 23 minutes. Grades 5 to 8.

Series of eight plastic raised relief models. Relates typical surface formations to subsurface structures that are shown as graphic cross sections on each model. Helps students to better understand the development of the landscape and the factor and force influencing the development. Geologic features are numbered and keyed to a comprehensive study guide. When combined, the 8 individual models form a continuous 8-foot long graphic landscape and landform reference. Each model is 12" x 15", printed in full color on durable plastic, thermo-formed and reinforced with rigid foam.
